RESUMEN
Chronic Obstructive Pulmonary Disease (COPD) is a common disease associated with significant morbidity and mortality that is both preventable and treatable. However, a major challenge in recognizing, preventing, and treating COPD is understanding its complexity. While COPD has historically been characterized as a disease defined by airflow limitation, we now understand it as a multi-component disease with many clinical phenotypes, systemic manifestations, and associated co-morbidities. Evidence is rapidly emerging in our understanding of the many factors that contribute to the pathogenesis of COPD and the identification of "early" or "pre-COPD" which should provide exciting opportunities for early treatment and disease modification. In addition to breakthroughs in our understanding of the origins of COPD, we are optimizing treatment strategies and delivery of care that are showing impressive benefits in patient-centered outcomes and healthcare utilization. This special issue of Respiratory Medicine, "COPD: Providing the Right Treatment for the Right Patient at the Right Time" is a summary of the proceedings of a conference held in Stresa, Italy in April 2022 that brought together international experts to discuss emerging evidence in COPD and Pulmonary Rehabilitation in honor of a distinguished friend and colleague, Claudio Ferdinando Donor (1948-2021). Claudio was a true pioneer in the field of pulmonary rehabilitation and the comprehensive care of individuals with COPD. He held numerous leadership roles in in the field, provide editorial stewardship of several respiratory journals, authored numerous papers, statement and guidelines in COPD and Pulmonary Rehabilitation, and provided mentorship to many in our field. Claudio's most impressive talent was his ability to organize spectacular conferences and symposia that highlighted cutting edge science and clinical medicine. It is in this spirit that this conference was conceived and planned. These proceedings are divided into 4 sections which highlight crucial areas in the field of COPD: (1) New concepts in COPD pathogenesis; (2) Enhancing outcomes in COPD; (3) Non-pharmacologic management of COPD; and (4) Optimizing delivery of care for COPD. These presentations summarize the newest evidence in the field and capture lively discussion on the exciting future of treating this prevalent and impactful disease. We thank each of the authors for their participation and applaud their efforts toward pushing the envelope in our understanding of COPD and optimizing care for these patients. We believe that this edition is a most fitting tribute to a dear colleague and friend and will prove useful to students, clinicians, and researchers as they continually strive to provide the right treatment for the right patient at the right time. It has been our pleasure and a distinct honor to serve as editors and oversee such wonderful scholarly work.

Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of mortality in the United States. Its symptoms, comorbidities, and sequelae also result in high morbidity and healthcare costs. The impact of progressive dyspnea, fatigue, exercise intolerance, and recurrent exacerbations in patients with COPD can be devastating to their quality of life. Un-addressed, these symptoms often result in depression and social isolation, causing further decline in exercise tolerance and functional performance. Assessing the physiologic, pharmacologic, and psychosocial factors that influence these elements can be challenging in the primary care setting. The present article describes a practical approach to assess functional performance and outlines pharmacologic and nonpharmacologic strategies-particularly self-management education and pulmonary rehabilitation-to improve quality of life indicators.

Numerous studies demonstrate the importance of exercise training to improve endurance in patients with chronic obstructive pulmonary disease (COPD) and its positive effect on activities of daily living and quality of life. However, successful care of the individual with COPD also relies on recognizing that this person requires individualized care and non-pharmacologic modalities specific to their needs in order to cope with the various aspects of their disease. It is also important to note that improvement in quality of life is not necessarily related to improvement in exercise endurance alone. Comprehensive and effective pulmonary rehabilitation for the COPD patient needs to encompass several components to provide benefit for the spectrum of symptoms of COPD beyond exercise tolerance and dyspnea to ultimately improve quality of life.

Involuntary exposure to environmental tobacco smoke (ETS) is a serious and entirely preventable public health hazard. It has become clear that ETS adversely affects the health of all who breathe its toxins. Independent of active smoking, ETS exposure is a modifiable risk factor for chronic obstructive pulmonary disease. The expanding body of research presented in this article provides evidence that the damaging consequences of ETS reach far beyond the lungs. Having been determined the third leading cause of preventable death in this country, this is a problem that must be addressed aggressively.

Exertional dyspnea often causes patients with chronic obstructive pulmonary disease (COPD) to unconsciously reduce their activities of daily living (ADLs) to reduce the intensity of their distress. The reduction in ADLs leads to deconditioning which, in turn, further increases dyspnea. Both dyspnea and fatigue are important factors affecting health-related quality of life (HRQOL). The functional status of patients relates to how well they perform ADLs. Activities, however, may not be severely limited until the disease becomes advanced. The elimination of an ADL depends on the necessity or desirability of that activity and the intensity of the associated symptoms. HRQOL is measured using symptoms, functional status, and a rating of their impact on the individual. The Pulmonary Functional Status Scale (PFSS) and the Pulmonary Functional Status and Dyspnea Questionnaire (PFSDQ) are 2 COPD-specific functional status questionnaires. Pedometers or accelerometers can quantify the levels of activity of patients with COPD. HRQOL is measured with validated multidimensional questionnaires that cover symptoms, physical, psychological, and social domains. Ideally, these instruments are discriminative (i.e., separate degrees of impairment) and evaluative (i.e., detect small changes after therapy). HRQOL questionnaires may be generic (e.g., Medical Outcomes Study Short Form-36 [SF-36]) and can measure favorable changes after intervention, such as pulmonary rehabilitation, or they can be disease specific with disease-related domains, e.g., Chronic Respiratory Disease Questionnaire (CRQ) with domains of dyspnea, fatigue, emotion, and mastery; and St. George's Respiratory Questionnaire (SGRQ) with domains of symptoms, activity, and psychosocial impact. A case is presented that depicts how these tools may be used to evaluate improvement with intervention in a patient with COPD.

Although pulmonary rehabilitation results in improvement in multiple outcome areas, relatively few studies in the United States have evaluated its effect on healthcare utilization. This study compared aspects of healthcare utilization during the year before to the year after outpatient pulmonary rehabilitation in patients with chronic obstructive pulmonary disease referred to 11 hospital-based centers in Connecticut and New York. Utilization data from 128 of 132 patients who originally gave informed consent were evaluated; their mean age was 69 years and their forced expiratory volume in 1 second was 44% of predicted. Forty-five percent had 1 or more hospitalizations in the year before beginning pulmonary rehabilitation. In the year after pulmonary rehabilitation, there were 0.25 fewer total hospitalizations (P = .017) and 2.18 fewer hospital days (P = .015) per patient and 271 fewer hospital days for the group. Hospitalizations for respiratory reasons also decreased significantly. Most of the reduction in hospital utilization was due to a decrease in intensive care unit days. The number of physician visits decreased by 2.4 in the year after pulmonary rehabilitation (P < .0001); most of this reduction was due to decreased visits to primary care providers. The estimated costs/charges for the aspects of healthcare utilization that we studied decreased by a mean of 4,694 dollars and a median of 390 dollars (P = .0002). This study suggests that pulmonary rehabilitation leads to a reduction in healthcare utilization.
